Wireless Accelerometer-based MIDI Controller

These prototype custom accelerometer boards transmit X-Y tilt data back to a receiver which formats and transmits it as a MIDI message. The on-board LEDs also show the status of the tilt with red in one direction, blue in the other.

The refresh rate is approximately 20 times per second, with a small amount of hysteresis built-in to avoid constant MIDI traffic if the board is still. Transmissions are are a 1Mbit data rate over a 2.4GHz link.

In this video, the two channels are controlling a filter in Ableton Live.

A few more details, as well as a pic of the receiver are on my flickr site:

And you just have build it!!!!

Great great!

What accelerometer do you use? DE-ACCM5G?

Awesome! I run karaoke using reaper as a mixer, would love to embed these in the mics to mute the mics if someone gets too rough with them.

Are you planning on open the specs or selling these or anything?
